我正在尝试基于类型文本的输入和突出显示文本进行简单的jQuery单词搜索.我怎么能这样做多个单词？此代码仅适用于单个字符.
<input type="text"/>
<div>John Resig
George Martin
Malcom John Sinclair
J. Ohn
Sample text
</div>
CSS
span {
background : red
}
JS
$("input").keyup(function() {
var mysearchword = $("input:text").val();
var word = mysearchword;
$( "div:contains('"+word+"')" ).html(function(i,html) {
var re = new RegExp(word,"g");
return html.replace(re,'<span>'+word+'</span>')
});
});
解决方法
如果您有一组预定义的元素来定位
var $para = $('.para')
$("input").keyup(function() {
$para.find('span.highlight').contents().unwrap();
var mysearchword = this.value.trim();
if (mysearchword) {
var re = new RegExp('(' + mysearchword.trim().split(/\s+/).join('|') + ')',"gi");
$para.html(function(i,html) {
return html.replace(re,'<span class="highlight">$1</span>')
});
}
});
span.highlight {
background: red
}
